Looks like it is trying to resolve Guid with name and it does not exist in AD. You can try to remove the same by launching ESM see below http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/exchange-2007-permissions-and-roles-part2.htmlVinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|
